Java 我的循环不会继续进行下一步

我的循环有问题

public static void me() {
    Scanner input = new Scanner(System.in);
    DecimalFormat df = new DecimalFormat("##0.00");
    int mew = 0;
    double mes = 0;
    boolean Curve = true;
    int cBool = 0;
    double cNum = 0;
    double mers = 0;
    double wmes = 0;

    //Input Midterm weight and score
    System.out.println("\nMidterm exam:");
    System.out.print("\tWhat is its weight (0-100)? ");
    mew = input.nextInt();
    System.out.print("\tExam Score ");
    mes = input.nextDouble();
    while (Curve){
        System.out.print("\tWas there a curve? (1 for yes, 2 for no) ");
        cBool = input.nextInt();
        if (cBool == 2)
            Curve = false;
        else
        System.out.print("\tHow much was the curve? ");
        cNum = input.nextDouble();
        Curve = false;
    }

    //calculate weighted Midterm score
    mers = (mes+cNum);
    if (mers > 100)
            mers = 100;
    wmes = ((mers/100)*mew);
    System.out.println("\tWeighted Exam score: " + df.format(wmes));}
}

问题是，当我为cBool输入2时，它将不会继续执行下一步，但是如果我为cBool输入1，然后为cNum提供一个数字，它将继续执行下一步

是否尝试隔离else块中存在的所有指令？ 由此：

else
System.out.print("\tHow much was the curve? ");
cNum = input.nextDouble();
Curve = false;

为此：

else

{

 System.out.print("\tHow much was the curve? ");
    cNum = input.nextDouble();
    Curve = false;

}

您正在设置

Curve=false

在第一次迭代后退出while循环。根据您已有的代码，当cBool==2时，您已经设置了Curve=false。因此，它不会继续下去，对于任何输入，rloop只会运行一次。此外，如果else部分是复合语句，请将其括在大括号中。else{System.out.print（“\t曲线多少？”）；cNum=input.nextDouble（）；curve=false；}始终在

{

if和

else

行之后使用

{/code>。否则，您会得到像这样的意外结果。这会迭代吗？当输入为
3
或
1
时需要什么？那么还需要循环吗？
